WAGON-AXLE.

SPECIFICATION forming part of Letters Patent No. 429,385, dated J' une3, 1890. Application filed November 25,1889. Serial No. 331,455. (Nomodelli To @ZZ whom t may concern,.- Y

Be it known that I, HENRY G. MITCHELL, of Racine, in the county ofRacine, and in the State of Visconsin, have invented certain new anduseful Improvements in Wagon- Axles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to wagon-axles; and it consists in certainpeculiarities of construction, as will be fully set forth hereinafterand subsequently claimed.

In the drawings, Figure l is a side elevation, partly in section, of oneend of an axle and its attachments constructed according to one form ofmy invention. Fig. 2 is an under side view of the'same with the skeinremoved. Fig. 3 is aperspective view of one form of my axlestrengthening bar. Fig. 4 is a plan view of one end of said bar. Figs.5,'6, and 7 are vertical transverse sections on the lines 5 5, 6 6, and7 7, respectively,`of Fig. 1. Fig. 8 is a View similar to Fig. 1, butillustrating another form of my present invention. Fig. 9 is an underside plan view of the same with the skein removed; and Figs. 10, 1l, andl2 are vertical transverse sections on the lines 10 10, ll 1l, and 12l2, respectively, of Fig. 8.

A, Fig. l, represents a wooden axle provided on the under sideV with a 1-shaped groove or recess B, the horizontal portions of which are mergedwith the vertical portion at the end, forming an upward-extending recessa, andthis groove B receives a correspending L- shaped metallicstrengtheningbar C, whose ends are rounded somewhat on the bottom, as atc2, and then swaged up into the portions b to iit the recesses a, andthence continued out at said elevated plane and formed into screw-boltsc. On the said screw-threaded ends c of the bar C are next placedwashers d, which t against the ends of the Wooden axle A, and next themare screwed nuts D. On top of the wooden axle `rest the hounds E, and onthem the bolster F, (said hounds and bolsterbeing preferably recessed orshouldered at their meetingpoints, as shown,) and, in the form shown inFig. l, being secured by clip G, plat-e e, and 5o nutsf H is a skeinslipped on each end of the axle, and having a reduced outer end 71with acontracted bore g, of a size just sufficient to receive thescrew-threaded end c of the bar C,'the bore of the rest of the skeinbeing of proper size and shape to receive the end of the wooden axle A,and also the washer d and nut D, the said'reduced end h of the skeinhaving a squared inner surface irn- 6o pinging against said nut D,'asshown, and being provided withk exterior screw threads to receive thehub-nut I when the Wheel is in place, while another nut t' is thenscrewed onto the protruding ends c of the bar C against the outerreduced end h of the skein, thereby tightly clamping all the partstogether.

In Figs. S to 12, inclusive, I show a modified construction wherein thebar (marked 7o C) is without any upward central iiange, being'a ilat barof iron bent up and rounded, as at c2, and then swaged up as before, ,asshown at b, and terminated in screw-bolts o, the attachment of the skeinand hub being precisely as already described with the other form of bar.This latter form C of bar may be used with clips, but is especially welladapted for use with bolts G', passing through the wooden axle, hounds,and bolster, and se- 8o cured by nuts, as shown.

My bars C C not only greatly' strengthen the axle, but form an admirablemeans of securing the axle-skeins and hubs to place.

Having thus described my invention, what I 8 5 claim as new, and desireto secure by Letters Patent, is-r In an improved wagon axle, thecombination, with the axlespindle having a longitudinal groove in itsunder side and an axle- 9o skein surrounding said spindle and having ascrew-threaded outer end, of a strengthening-bar embedded in the underside of the spindle and extending outward through the screw-threaded endof the skein, said end of the bar being externally screw threaded, a nutscrewed upon the end of the bar and lying Within the outer portion ofthe skein, a

nut also screwed upon the outer end of the county of Racine and' Stateof Tisoonsirn in bai' and abutting against the outer end of the presenceof two Wltnesses. i

the skein, and a nut screwed upon the outer o f MITCHELL end of theskein, ali substantially as de- HENRX G` 5 scribed. Witnesses:

In testimony that I Claim the foregoing I F. W. AINSWORTH,

have hereunto set my hand, at Racine, in the JOHN FAIRLEY.
